Adding users
by Dave Williams 08 Jun '00

08 Jun '00

I'm still struggling to devise a simple way to add large numbers of user accounts using csv files or similar. The users already exist on an Acorn Level 4 server and I want to move the users and passwords, transparently to a Linux server. I have no problem exporting the csv file but...... Anyone help with these points 1) useradd in RedHat does not appear to understand the -p option and it is not mentioned in the man pages. Does suse recognise this option and as a result allow a single line entry for a user and their password? 2) If I type useradd as root I get an error - "bash: useradd: command not found" but $PATH reports /usr/sbin as part of the path and this is where useradd is located. What am I missing? 3) Can anyone recommend a good source of information on writing shell scripts - I might then be able to fiddle around with the passwd command. Dave Williams

Ive finally installed Suse, got apache running, along with ftp, installed Squid 2, but having no luck. The config says the port is 3128, so if i set netscape etc to Proxy http 1921.168.1.1 port 3128 i expect to be going via the proxy, and get squids error pages... but trying to access a site outside the network (connection not setup yet), I get the normal "Netscape windows error - server down" What am i doing wrong.

Squid2

I have tried saying this before, but the list tells me that I am not a member at home, so I re-apply to the list and it then tells me that I am already a member. Oh hum! Anyway Thanks for all the help with Squid. It's now working, I haven't played with anything other than the following... Commented out the line... http_access deny all Added the line... http_access allow all - not sure of the effect of this as I've been busy elsewhere but it works. Sometimes the system will refuse to see an address and reports that it can not resolve the URL, but getting there. Thanks again. Adrian

Named and Squid2
by Derek Harding 29 May '00

29 May '00

Hi, In my last mailshot I left out my school eMail address; I've had to send from home because the school's ISP has been off line (again) all day. I echo the comments about named and squid not running out of the box. named needs careful planning and for first-time users I would suggest starting with a handful of addresses on your 192.168 site and getting it all sorted before creating your full list! squid2(.23) is very good once set up as a proxy/firewall/filter but some of the reporting tools are a little weak. It certainly benefits from being on a machine with a good quantity of RAM and good processing capacity, our system finds it a bit of a bottleneck (256k ISDN bandwidth in use all breaktimes and often during the lessons, too!). The same box is our internal webserver, mailbox, dhcp server, etc., etc., so it isn't too surprising that it slows down at times! It never crashes, either - unlike some systems I have to use. It would be useful if squid could read some of its configuration from include files, then adding to the filters would be more straightforward. Perhaps it can and I haven't found out yet. -- Best wishes, Derek Harding ICT & Network Manager, Warlingham School hardingd(a)warlingham.surrey.sch.uk

Re: Filtering etc.
by Derek Harding 29 May '00

29 May '00

Thanks to Alan for his comments and hints (Netnanny etc.). We don't have the e-mail problem because only staff have Internet e-mail (on the school ID!); students have to forward curriculum related mail via the relevant tutor and replies come back the same way. They do have internal e-mail from year 12 and up. We may extend this to years 10 and 11 after September but still internal only (using Pegasus). It is indeed a constant quest to restrict undesirable sites but that is what I (naively) expected of our ISP's filtering. Porno is the one that our students seem to want to try at present, though I have trapped several non-sexual but still inapropriate sites. What filtering apps. are going to come from the SuSE stable? -- Best wishes, Derek Harding ICT & Network manager hardingd(a)warlingham.surrey.sch.uk

Filtering out pornography etc.
by Derek Harding 29 May '00

29 May '00

Hi Folks, You may have noticed that your ISP doesn't filter pornographic and "bad taste" sites very well. Some of them wait for schools to find the offensive sites and then inform them so that in a fortnight or so they can add the sites to their filter (including some of the supposedly school dedicated sites such as schoolzone). For our school (250+ machines, most "internetable") that situation is unacceptable. I use squid2 (and the url-regex function) to provide both proxy services and a first barrier against "bad sites" including foreign languages (try www.baise.net through your filter for example) and bestiality sites (which masquerade as respectable sources). I also block obvious hacking sites, several chats and some plain bad taste sites. It might be useful if someone could collate lists of these sites so that there is a general list new gateway servers can forbid? Any volunteers? (Sorry, I can't take it on just yet.) -- Best wishes, Derek Harding derek(a)lagham.zetnet.co.uk

Linux User magazine ...
by kevin.taylor＠powerconv.alstom.com 26 May '00

26 May '00

Just a quick note, I received my free copy of the 'Linux User' magazine (first issue was due out in May) and found it an excellent resource. It is geared up (so I believe) to be a mag for 'IT Decision makers and professions' and it certainly has a better slant than its high-street counterparts ... They are taking requests for free subscriptions at the moment, and I may well be worth some of you having a look. see http://www.linuxuser.co.uk (They will also be at the Linux Expo, along with the other UK based mag Linux Format. I haven't seen a copy of the latter yet, so cannot comment ...) Note: I am in no way connected with Linux User - I am just pleased to see a UK based Linux mag at last ! Kevin.
